HW-33 (25 points) Superheated steam at an absolute pressure of 20 MPa and a temperature of 560°C flows into the turbine of a Rankine cycle. The absolute pressure at the turbines outlet is 0.5 bar, and liquid exits the condenser at an absolute pressure of 0.4 bar and a temperature 75°C. The absolute pressure is increased to 20.1 MPa across the pump. The turbine and pump have isentropic efficiencies of 81% and 85%, respectively. Cooling water enters the condenser at 20°C with a mass flow rate of 70.7 kg/s and exits the condenser at 38°C. For the cycle, determine a) the mass flow rate of steam, in kg/s. b) the thermal efficiency
